Can Animate Objects be made permanent? If so, I'd Animate pretty much everything in my house, and quite a few things outside my house too.

Then I'd animate my house.

Yes they can. There are two methods: Cast the spell and make it permanent with permanency (which can be dispelled), or make them as constructs in their own right with Craft Construct (which cannot be dispelled).

I had a witch that animated her house and used it to attack an adventuring party. Nearly crushed them into the earth it did.

Unseen Servant seems too useful and too easy a spell to leave home without it functioning. In fact, wizards/sorcerers in our group even at low levels always have it and Mage Armor cast when they get out of bed.

Unseen Servant is not very useful for the adventuring wizard as a long-term 'buff'.

The fact it only moves at a 15, means it will usually get dispelled as soon as you start moving from point A to point B, unless you willingly only ever walk at half speed.

'Tis fine if you're sitting in one spot... lots of suckage once you start traveling.

Um. Generally you will be walking at half speed. Anything faster is effectively jogging.

Carry it? It appears to have no weight of its own. Just transport the invisible servant via piggyback and send it out whenever you need something done.

It's also shapeless. I don't know how you'd carry something that has no shape.

I realize there are a lot of different ways you could interpret Unseen Servant. It could be an actual invisible being, but I think that if it was, there'd be a lot more description. To me, the spell sounds more like a semi-autonomous telekinesis.

What would an Unseen Servant look like with See Invisible or Glitterdust?
